This providesa simple means vfor adapt' in g the headlight for either aone or two l wire system. When it vis to be used on a are connected tothe arms 27 and 28, a screw- 5' tion of gthe bulb with res 4 andcomprises a per one wire system the one wireis connected to the arm 27and a screw long enough toconnect the arm 28; and the casing A is'used,l

thus providing a ground orthe one sideflfprovided aheadlight structurewhich' is of the light. When the headlight isV to be used with a twowire system the two wires being' used on the contact 28 which-is shorterthan the thickness of the block' so that it will not ground the contact.f

Provision is made for adjusting the posiect to the reflector orated cap30 seof the sleeve 12. A passes through the perforacured on the free end13 threaded` bolt 31 tion in the cap 30 and engages thenut 18 ofv lug'member-16. A collar 32 is pro-` the vided) on the bolt`31' to preventlongitudinal movement `of the bolt 31 through the cap 30. The head ofthebolt '31 is slotted to accommodate a screw driver or the likefor rotatinthe bolt 31 to move the plug 16 andthe bulb 22 with respect to thereflector 4. The

rovi'siou of slidlng'contacts on the lug and lock makes vit -unnecessaryto botiier withl wires when changing bulbs and the w'res 33 are brought44into the near o f thecasmg A through a bushed aperture Maudl connectedto the rcontacts 27 and7 28. 4

From the foregoing destripaon-a will be.

inserted into and removed from the casing i without necessitatingtheremoval of 'the glass front of the casing. It will be further*observed that I have provided a headlight structure in which the bulband socket carrying member may be removed from and replaced inthe'casing Without thetrouble of connecting and disconnecting Wires.

It Vwill be 'further observed that I have adapted t0 be used with.either a one wire or".

two wire system.

What is claimed is: In vehicle headlamp,` a casing, a reflector in saidcasing, a tubular member extend- Vingaxially from said reflector throughan opening provided in-the rear wall of 'said' 'carried by said plug andadapted for the re.

caption. of a lamp bulb vof a diameter less than' the diameter of Vsaidtubular member,

l bulb contactsfcarried by said plug, and stationary contacts carried bysaid caslng and arranged for sliding contacts of said plug.
